In order to optimize their storage capacity, super capacitors are introduced to the renewable energy system which creates a voltage source control that dictates the frequency and AC voltage in the system and mainly responds to sudden energy unbalances while a current source control receives control input from SC voltage difference and mitigates the error-signal in order to fulfill the necessary energy demand on the system.
